lllllllllllH IIIIIIIIH UNITED STATES PATENT OFFICE.

Application filed May 12, 1917.

To all whom it may concern:

ratus for compressing and retaining under compression a. spring which normally sur rounds a valve stem while a retaining pin 'may be inserted or removed from the stem.

In a practical application of a device of this kind, the space wherein it is to be used is enerally limited.' F or this reason it deslrable to have a compact and simple instrumentality with few parts which when applied 'to an automobile, for example, may be used without the removal of the manifolds. It is likewise desirable to provide for quick adjustment of the parts and ar-' ranging them so that when thus adjusted this same'adjustmentmaybe utilized for a number of machinrs. It is likewise advisable to have a structure wherein the device may be, when not in use, placed flat upon the ground in which position it is not likely to be bent or disturbed in .a manner which mightihtcrfere with the normal working ot'its parts. 1

It is the primary object of the present invention'to provide an instrumentality which will'embody the features above'en'u'merated and'which in addition thereto will have but 1 few parts readily assembled and capable of quick adjustment and being adapted for use in' practically all of the standard engines on the market at the present time.

Other objects and advantageswill in part be apparent and in part be brought out in the descriptionwhich follows.

Specification. of Letters Patent.

VALVE-LIIFTER Patented Mar. 5, 1.918.

Serial No. 168,168.

Fig. 3 is a detail View in perspective of a portion of the device. Referring specifically to the drawings, the numeral 1 designates a body portion or back plate having at its upper end an angulated extended portion 2 which is in turn provided at its outer extremity with a valvehead engaging member 3 threaded into the end of said arm and capable of being locked in different positions of adjustment for which purpose a thumb piece 4 and clamp ing nut 5 may be used.

Upon the back plate or body portion 1 there are mounted straps 6 which are adapted to encircle and retain in sliding engagement with. said back plate a slida-ble member 7. This member has at its lower portion an angulatcd arm 8 which at its outer extrem ity is formed into a fork member 9.

Upon the upper extremity of this mom-- ber 7 there is pivotally mounteda lever 8' which-lever is pivoted at its end to the end of the member 7.

Connecting this lever and one of the strap members 6 there is a link 9 the lower portion of which is secured to the strap suitably as by means of a bolt '10 the other end thereof being pivotally connected to lever 8 as by means of a. connecting member 11.

For the purpose of efl'ecting an adjustment between the lever 8 and one of the straps 6 there are provided a plurality of openings 12 on. the lever intermediate its ends and the link 9 may also be provided with additional openings 13 whereby the sweep of the lever may be changed by chang ing the location of the pivot point 11 n the various openings 12 in the lever or by moving the bolt 10 into one of the openings down by means of the thumb nut onto a valve head 14 the lever 8' being preferably in raised position as shown. The spanner member 9 is made to encircle a washer or the like 15 which is usually providedonthe lower end of a spring 16 whichen'circles the valve stem 17. When in this position, the lever 8 is then pressed down into the position shown in dotted lines whereupon the spring is compressed to the position indicated in dotted lines and the'retaining pin 18 may then be removed.

The location of the pivot pointv 11 which connects the link 9 with lever 8' is so arranged that when the lever is pressed down into the position shown in dotted lines in Fig. 1 the pivot point 11 will be out of alinement with the oflthe lever and the lower end of the link, thus effecting a locking of the lever in its lowered position.

From the foregoing it will be apparent that the valve lifter which comprises the subject matter of this invention provides a quick adjustment for the valve head engaging member which may then be locked. in its adjusted position, and then a positive lever actuation of the spring compressing member by means of a lever andlink connection which makes a very practical arrangement and effects a quicker compression of'the spring than was possible in devices wherein the threading of the member 3 was utilized to compress the spring.

It will also be apparent that the added adjustment provided by the openings arranged in the link 9 and lever 8 gives this device a large range of uses while its flat and compact form permits its being run over by a ca'r,-for instance, without impairing its utility or damaging its working parts. 7

\Vhile I have disclosed the invention in the embodiment herein illustrated, it will be understood that. I do not. desire to limit myself to the precise form of this disclosure, as such changes may be made inthe construction and general arrangement as defined by the appended claims.
